The answer is, 24x
The answers are ± 625
ok lets let x=4. The square root of 4 to the 2nd power + 4= 8. The square root and power of 2 cancel out? Is that what you mean?
x^2 = 54; take the square root of both sides, so x = +/- square root of 54 , or simplified is +/- 3 times square root of 6.
Press 2ND and then the square root sign (above x2). Then type the number you want to find the square root of. Press ENTER to see the answer.
(5x - i)(5x + i) where i is the imaginary unit equivalent to the square root of negative one.
(5x - i)(5x + i) where i is the imaginary unit equivalent to the square root of negative one.
square root of c to the second power is c

Isnt that just the square root of 64, being 8...?
Press 2ND and then the square root sign (above x2). Then type the number you want to find the square root of. Press ENTER to see the answer.
x^2 plus 4 = 0x^2 = -4square root both sidesx = the square root of -4x = 2i
A "square" (2nd power) is the result of multiplying a number by itself. For example, the square of 3 is 9 because 3 x 3 = 9. A "square root" (-2 power) is in the opposite exponential direction: you are finding the number which multiplied by itself will equal your given number. Using the same example, the square root of 9 is 3, because 3 x 3 = 9. Except for numbers that are squares of integers, most square roots will be long non-repeating decimals. (The square root of 2 is 1.414213562...)
